RAILWAY-CAR.

SPECIFICATION forming part of Letters Patent No. 780,764, dated. January 24, 1905.

Application filed July 25,1903. Serial No. 166,938-

To a whom, it may concern:

Be it known that I, SPENCER OTIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Cars, of which the following is a specification.

My invention relates to that class of cars known as freight-cars, and particularly to the class of freightcars known as dumpcars, having special reference to the arrangement of longitudinal and cross sills, so as to provide for the forming of an efficient bodybolster, all of which will more fully'hereinafter appear. 7

The principal object of the invention is to provide a simple, economical, and efiicient frame for railway-cars which provides, in effect, an eflicient body-bolster.

The invention. consists principally in a railwaycar in which there are combined a plurality of longitudinal sills centrally disposed, a plurality of deck-beams laid thereon and extending from side to side of the car, and a bar transversely arranged under the longitudinal 'sills so as to embrace the same and form in connection therewith a body-bolster.

The invention consists, further and finally, in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of one end of a car as it apwell-known elements which, if set forth herein, would only tend to confusion, prolixity, and ambiguity.

In the art to which this invention relates it the art, however, this cannot always be accomplished in that there are transverse sills or beams arranged above the body-bolster of the car, so that if swinging sections or dumping-doors be arranged over the truck a space will be left between the deck-beam over the body-bolster and the adjacent edge of the door through which fine materialsuch as ore, gravel, and thelikemay percolate to fall into the bolster mechanisms.

The principal object of this invention,there fore, is to remove this objection by providing a car-frame so constructed and arranged that the deck-sill usually placed above the bodybolster may be dispensed with, thus permitting the'use of a dumping-section which will extend over and across the bodybolster to the next adjacent deck-beam,so as to discharge all of the material over the car-truck without letting any of it percolate, as heretofore, into the bolster mechanism, and which will at the same time provide a structure to gitudinal sills a a, centrally disposed and ar ranged at a lower level than usual. These longitudinal sills extend from end to end of the car and practically flush with the outer sides of the end sills Z which are arranged upon the outer upper ends of the longitudinal beams. A plurality of deck-beams c is also provided and laid upon these longitudinal beams and extend from side to side of the car. It will be noticed that there is no transverse sill or deck-beam arranged over the or-' dinary bolster mechanism or at the point where the center of the truck is usually placed.

It will be readily seen that some means must be provided for sustaining the car body on the truck as a substitute for the usual bolster mechanism, and in order to provide such means I make what 1 term a new and improved body-bolster, formed of anupper bar (Z, transversely arranged across and laid on the upper surface of the longitudinal sills and extending downwardly at each end. I next provide a lower bar (2 and arrange it transversely of such longitudinal sills and against their lower surfaces. This lower bar extends outwardly beyond such longitudinal sills to a point where it provides the usual side bearings f, thence extends upwardly and inwardly-in other words, is inclined, as at g until it meets the side sills and is connected thereto and to the downturned ends of the upper bar by means of bolts it. This lower bar is also provided with the usual center bearing i, the useof which is well known and needs no further description here. It will also be seen on examining Fig. 1 that this body-bolster is arranged midway between the end'sill and the next adjacent deck-beam and that there is therefore no necessity for a deckbeam or transverse sill over such bod y-bolster.

In using these improvements with a dropbottom dump-car I provide in connection with the usual upwardly-extending side boards 7 and end boards is a drop-bottom formed of a plurality of swinging sections Z, pivotally secured at their inner edges to the framework of the car at each side of the longitudinal center thereof, so that they may be dropped down to form inclined discharging-aprons, as shown to the right of Fig. 2, and discharge materials to either or both sides of the track. Again examining Fig. 1, it will be seen that the first swinging section at each end of the ear extends from the inner side of the end sill across and over the improved body-bolster to the next adjacent deck-beam without making any joint or crack, so that fine loose material may be carried in the car, there being at no time any danger of leakage of material to affect the operation of the bolster or truck mechanism. Again, it will be seen that this peculiar construction andarrangement of elements permits of the discharge of material from one end of the car to the other, over as well as between the trucks.
